The turquoise and December

December is the winter- and Christmas month. It is also "the dark month". The name 'December' comes from the Latin word Decem which means 'ten'. Before the modern-day calendar, a year had only ten months. December, the tenth month, was the last. The sky blue variant of the turquoise fit the month of December best. Later on, two months were added: July and August. These are named after the Roman Emperors Julius Cesar and Augustus. Besides turquoise, the precious gem tanzanite is also December's birthstone. turquoise earrings

The Turquoise as a gem and in jewelry

The turquoise thanks its name to its color. This color is widely used in clothing, houses and fashion items. Some believe the stone has medicinal gifts such as described above. This is one of the reasons turquoise is so popular. According to color experts, the characteristic blue-green color stands for deep sympathy and compassion. But because the stone is a combination of two colors, it also stands for love, peace, authority, truth, future, and adaptability. turquoise necklace
